2 Dollars - Charles III Butterfly

Niue's status as a prolific license issuer for novelty bullion has made it the nominal authority on hundreds of collector pieces it has no organic connection to. This butterfly series falls squarely in that category — a New Zealand-administered territory of roughly 1,500 people lending its legal tender framework to a product developed and marketed almost entirely by a third-party mint for the global collector market.

The two-ounce specification is deliberate: it gives manufacturers enough silver surface area to execute detailed enameling or shaping work that a standard one-ounce planchet cannot accommodate.
